China’s EV Battery Swapping Sector Sees 2025 Surge as CATL and Nio Accelerate Network Expansion
China's battery swapping industry has entered a "golden age" of rapid expansion in 2025, driven by surging electric vehicle (EV) demand and aggressive infrastructure rollouts. The sector is rapidly shifting from isolated pilot projects to a standardized, mass-market adoption phase, fundamentally reshaping the refueling ecosystem for the world's largest EV market.
Contemporary Amperex Technology is spearheading this consolidation through a "dual-line" strategy targeting both passenger vehicles and heavy trucks. The battery giant has secured strategic partnerships with major automakers including GAC Group and FAW Group to launch compatible models, while aiming to complete 1,000 "Choco-SEB" stations this year and targeting over 2,500 stations across 120 cities by 2026.
Concurrently, NIO is actively opening its historically proprietary network to the broader industry. As of December 30, the company has established 3,665 swap stations globally, with a focus on penetrating county-level administrative zones to bridge the "last mile" gap in charging infrastructure. This push towards interoperability marks a critical pivot from "exclusive" networks to an "industry universal" model.
This infrastructure boom coincides with renewed capital market interest, evidenced by Aulton New Energy filing for a Hong Kong IPO in December. However, despite policy support and projected compound annual growth rates exceeding 30% for swap stations through 2030, the sector continues to grapple with high capital expenditures and the complex challenge of unifying technical standards across competing manufacturers.
Consolidation of Competitive Power
The competitive landscape in 2025 is defined by the aggressive execution of roadmap targets by key industry players. CATL has diversified its approach through its "Choco-SEB" solution for passenger cars and "QIJI" for heavy trucks. In April, the company signed agreements with five major automotive groups—including Changan Automobile and BAIC Group—to release 10 new swap-capable models. Further expanding its reach, CATL partnered with rental giant CAR Inc. in August to deploy over 10,000 swap-capable vehicles across 2,000 outlets.
NIO Inc. remains a dominant force, leveraging its technological lead to expand coverage. By the first half of 2025, the company achieved "county-to-county" coverage in over 1,200 administrative zones. The automaker plans to scale its next-generation infrastructure, with its fourth-generation stations currently deploying in regions like Shanghai and Zhejiang, and a fifth-generation station pilot underway for mass deployment in Q1 2026.
Meanwhile, Aulton New Energy is positioning itself as the largest independent third-party provider. According to its prospectus, the company had connected 521 stations by mid-2025, serving over 130,000 registered vehicles. Its push for a public listing underscores the capital intensity required to compete with automotive and battery OEMs.
Policy Tailwinds and Market Forecasts
Government policy remains a primary catalyst for the sector's 2025 acceleration. In September, the National Development and Reform Commission (NDRC) released a "Three-Year Action Plan" explicitly including battery swapping in its capacity expansion goals. The mandate aims for swap networks to cover major urban clusters and logistics corridors by 2027. Local governments, including Jiangsu and Guangdong, have followed suit with subsidies and plans to integrate swap stations into key transport hubs.
Market projections reflect this regulatory support. Data from China Insights Consultancy (CIC) indicates that sales of swap-capable vehicles are expected to grow from 269,000 units in 2024 to 1.13 million by 2030, representing a compound annual growth rate (CAGR) of 27.1%. Correspondingly, the number of swap stations is forecast to jump from 4,400 to 24,000 over the same period, a CAGR of 32.5%.
Financial Burdens and Standardization Barriers
Despite the growth trajectory, the industry faces significant headwinds regarding profitability and standardization. The sector suffers from "standard segregation," where customized battery specifications prevent cross-brand compatibility, leading to resource redundancy. This fragmentation increases the already high fixed costs of land, equipment, and grid connections.
Financial pressure remains acute. Aulton New Energy reported a net loss of RMB 157 million (US$22.45 million) in the first half of 2025, following consecutive annual losses. Similarly, NIO Inc. has invested approximately RMB 1.8 billion (US$257.4 million) in charging and swapping infrastructure to date, with plans to invest an additional RMB 5 billion (US$715.8 million) over the next decade. Industry consensus suggests that alleviating these financial pressures depends heavily on achieving scale effects, which in turn requires a unified battery standard that has yet to fully materialize.
Commercial Vehicles Drive Early Adoption
While passenger vehicle adoption grows, the commercial sector, particularly heavy trucks, has emerged as a high-efficiency use case. The "QIJI" swap solution by CATL addresses the specific needs of heavy transport, where long charging times compromise operational efficiency. Swapping allows heavy trucks to refuel in minutes, maximizing uptime for logistics operations.
CATL has moved quickly to dominate this niche. In May 2025, the company launched a project in Shanxi province to build 41 swap stations and deploy 1,000 heavy trucks, with long-term plans for 50,000 vehicles in the region. Similar networks are being established in Shaanxi province, creating a "cross-regional" swap corridor. The predictable routes and high utilization rates of heavy trucks offer a clearer path to profitability compared to the private passenger car market, providing a strategic anchor for the broader swapping ecosystem.
